Not only do these companies supply the typical medical instrumentation (as the name would suggest), but also the atypical. When we think of medical instrumentation, respirators, ultrasonic cleaners, and oral cameras all come to mind. What one of the companies in this category does is also provide a very unusual service, but very useful nonetheless. They manage a cellular storage databank with thousands of different cellular samples that can be used by hospitals for different purposes. Along with the cellular storage bank and the mainstream medical instruments, there are also a few companies that have a needle-free jet injection system that, since there are no needles used, virtually eliminates accidental needle pricks and the chance of contracting a bloodborne pathogen.
